2. PRODUCT DESCRIPTIONS

Thank you for purchasing JBL Control 400 Premium Coverage series Ceiling Loudspeakers.

Read through this manual to familiarize yourself with the features, applications and precautions before you use these products.

The JBL Control 400 Premium Coverage series Ceiling Loudspeakers is a line of premium, in-ceiling loudspeakers that offer superior sound and consistent coverage. It features JBL's proprietary conical Radiation Boundary Integrator® (RBI™) technology which offers extremely even pattern control which often allows use of fewer speakers in an installation. The Series includes six models to suit various performance & design requirements. Housed in an elegant industrial design, they deliver outstanding performance and reliability.

Control 442C/T is an ultra-compact in-ceiling satellite speaker with 2.5" mid/high driver. The speaker can be set for low-impedance (16Ω) operation or can be driven by either a 70V or 100V distributed speaker line. (SKU# is JBL-C442C/T)

Control 445C/T is a two-way in-ceiling loudspeaker with a coaxially mounted 5.25" woofer and 3/4" tweeter featuring JBL's proprietary conical Radiation Boundary Integrator® (RBI™) technology. The speaker can be set for low-impedance (8Ω) operation or can be driven by either a 70V or 100V distributed speaker line. (SKU# is JBL-C445C/T)

Control 447C/T is a two-way in-ceiling loudspeaker with a coaxially mounted 6.5" woofer and 1" tweeter featuring JBL's proprietary conical Radiation Boundary Integrator® (RBI™) technology. The speaker offers extended bass response for a warm, full-bodied tone. It can be set for low-impedance (8Ω) operation or can be driven by either a 70V or 100V distributed speaker line. (SKU# is JBL-C447C/T)

Control 447LP is a shallow, low-profile version of the Control 447C/T for locations with limited space above the ceiling. The speaker features JBL's proprietary conical Radiation Boundary Integrator® (RBITM) technology. This model has the same diameter footprint as the Control 447C/T offering uniformity of appearance in the ceiling. The shallow LP model can be used along with other full-depth models from the series for a consistent sound character. (SKU# is JBL-C447LP)

Control 447HC is ideal for use in high ceiling applications and highly reverberant spaces. It features a narrow 75° coverage pattern, which helps minimize sound reflections off of room surfaces, resulting in improved speech intelligibility. Control 447HC features the same sonic character as the Control 447C/T with a coaxially mounted 6.5" woofer and 1" tweeter and JBL's proprietary conical Radiation Boundary Integrator® (RBITM) technology. (SKU# is JBL-C447HC)

Control 440CS/T is an 8" high power in-ceiling subwoofer designed to produce powerful bass performance. It is perfect for in-ceiling sound systems requiring higher fidelity sound with low end extension. The Control 440CS/T also features a built-in passive crossover network enabling it to be used as part of a subwoofer-satellite system driven by a full-range signal.

4. INSTALLATION PREPARATIONS

The entire installation can be accomplished, if necessary, without requiring access above the ceiling. Bracketry for use with either suspended ceilings or sheetrock ceilings is included. The speaker is held securely in place via "dog-ear" mounting tabs which lock into place. Inputs and loop outs to the next speaker are attached to snap-in-place connector (included) which can be prewired before installing the speaker for ultra-fast snap-on installation.

OPTIONAL PRE-INSTALLATION BRACKETS

IN MOST CASES, NO BRACKETS OTHER THAN THE ONES INCLUDED WITH YOUR SPEAKER ARE REQUIRED.

Everything needed for most installations of these loudspeakers is provided with your Control Contractor ceiling speaker.

However, a particular procedure that is sometimes used for installation into sheet rock (typically gypsum board) can be facilitated by the use of JBL's optional pre-installation brackets before the sheetrock is installed. The pre-installation bracket provides a bracket to which wiring can be strapped in-place behind the sheetrock. It can function as a cutout template when many cutouts are to be made in a production-line style installation. And it can reserve a location in the ceiling prior to the sheetrock getting installed. Two types of pre-installation brackets are available from JBL Professional as optional accessories:

1. The optional NC NEW-CONSTRUCTION BRACKET is made of flat sheet metal, with wings to attach to the building structure. Holes are drilled for nails or screws at 16 inches (406 mm) and 24 inches (610 mm) on-center. Additional holes can be drilled by the installer at other spacings up to a maximum of 24-3/4 inches (630 mm) apart. Sheet rock installs after the bracket gets installed, and the bracket provides a template for blind cutout of the hole in the sheet rock. For this process, the sheet rock is typically cut with a router-type cutting tool, using the bracket ring as a cutout guide.

Figure 1: Optional NC New -Construction Bracket

1. The optional MR PLASTER-RING BRACKET (or "Mud Ring") contains a circular offset, forming an edge guide for sheet rock plastering. The bracket has wings that attach to the building structure. Sheet rock is typically either precut or cut with a rotary cutting tool using the outside of the plaster ring circle as a guide. The sheet rock hole is then plastered (or "mudded") up to the ring to create a seamless cutout.

USING INCLUDED C-BRACKET WITH SHEETROCK

For most installations, the INCLUDED C-shaped backing plate provides adequate reinforcement to the ceiling material, distributing out the clamping force from the dogears. Even if one of the dogears lands on the opening between ends of the C, the rest of the dogears will land on it, so will be sufficient support for sheetrock installations.

CEILING CUTOUT SIZES

Packaged with the speakers are cardboard cutout templates for scribing the cutout hole onto your ceiling surface.

Table 2: Cutout Sizes

Model Cutout Size (diameter)
Control 442C/T 104 mm (4.1 in)
Control 445C/T 223 mm (8.8 in)
Control 447C/T, Control 447LP	282 mm (11.1 in)
Control 447HC, Control 440CS/T	307 mm (12.1 in)

OPTIONAL BG (black) and SG (square) GRILLES

Optional round black and white square grilles are available. The JBL-MTC-xxxBG grilles are round Black Grilles that can be utilized instead of the included stock white grille when black is called for. Alternatively, the stock white grille can be painted (see below). The JBL-MTC-xxxSG are white Square Grilles that can be utilized instead of the included stock grille when a square grille is desired. These grilles can be painted to the desired color (including black). These grilles completely cover the speaker assembly.

5. STEP-BY-STEP INSTALLATION AND WIRING

The installation system has been designed so that the entire installation can be accomplished from beneath the ceiling for instances when access above the tile is not possible or practical. However, in some cases it may be easier -- with removable ceiling tiles, for example -- to access from both the top and bottom of the ceiling tile during various phases of the installation.

Note: the wiring method shall be in accordance with:

(1) In Canada, CSA C22.1, Canadian Electrical Code, Part I, Safety Standard for Electrical Installations, Section 32

(2) In the United States, NFPA 70.

Step 1 – Cut the Hole. Cutout the hole size either by tracing the included cardboard cutout template or by scribing a hole using the cutout size chart above. Use a safe tool such as a jigsaw to cut the hole and proper eye protection. Be precise, not deviating from the cutout diameter by more than 1/16th of an inch (1.5 mm). Pull the wiring through the cutout hole.

Figure 3:
Hole Cutout
(Shown: Wire in flex conduit)

Step 2 – Insert Backing Hardware Through the Hole.

Packaged with the speakers are two types of backing hardware – a C-shaped backing-plate ("C-ring") bracket and two tile rails.

Suspended Ceilings – Insert the C-ring through the hole cut in the ceiling tile (or set it in place from above the ceiling, if there is access). Place the C-ring around the hole with the tabs located as shown on Figure 4. Insert the tile rails through the cut hole in the ceiling tile. Snap the two rails into the two tabs in the C-plate and align the rails so that the ends extend OVER the T-channel grid on the side of the tile. Secure the rails onto the C-ring tabs by inserting a screw though each tab into the rail. This can all be accomplished from below the ceiling tile, if necessary.

FOR SAFETY: IMPORTANT TO USE BRACKETS

ALL included support brackets - C-ring and tile rails -- MUST be used when installing into suspended ceiling tiles.

Figure 4:
C-Bracket and Tile Rail Positioning on Ceiling Tile

Tile Rails: The tile rails are designed to fit either standard 24-inch-wide tiles or 600-mm-wide tiles. The tile rail pieces do NOT physically attach to the T-grid struts. Instead, the inverted-V shape at the ends of the rails sits ABOVE the T-grid strut. During normal operation, the rails are supported by the edge of the tile. In the unlikely event that the tile comes out or falls apart, the ends of the support rails are designed to catch onto the T-grid, providing secure support to hold the loudspeaker assembly in place.

Optional accessory Tile rails JBL-MTC-48TRX4 (pack of 4 Tile Rails) are also available for installation into larger 4' x 4' (1200 x 1200 mm) ceiling tiles.

Vibration Reduction: These loudspeakers can generate substantial audio output, which can cause buzzing of the ceiling materials or structure. Depending on the character of the ceiling tile and structure, the installer might need to place neoprene or other dampening material under the tile rails or the edges of the tiles to eliminate rattles.

Cutout Placement: The tile rails are pre-punched with attachment holes along their length. Placement is not limited to the center of the tile as is the case with many other tile rail support systems.

Non-Suspended Ceiling Types – For non-suspended ceiling types, the C-ring can be optionally used by itself to shore up the ceiling material and to spread out the clamping force from the tab clamps. Insert the C-ring through the cut hole in the ceiling and place it on the top side of the hole before inserting the speaker.

Step 3 – Plugging connectors into connector sockets in the speaker's terminal cup.

Fully loosen the captive TERMINAL COVER retaining screw that is on the top panel of the backcan. This screw remains captive in the terminal cover (do not fully remove it).

Step 4 – Connect the Wiring to the Removable Locking Connector(s) – Two 2-pin removable locking connectors are included with the speaker – one for IN and the other for LOOP OUT. Connect the wiring to the removable locking connectors by stripping the insulation back about 5 mm (about 3/16 inch) – stripping the wire longer risks shorting and stripping the wire shorter risks a poor connection to the connector. Insert the bare end of wire into the connector and screw down the hold-down screw until tight using a small flat blade screwdriver. Tighten any unused screws to avoid vibration. Double-check that the wires are not frayed, and that bare wire is not exposed (either of which can lead to shorting between the wires).

Figure 24: Insert Speaker through Ceiling Cutout

Tighten Dogears -- IMPORTANT -- For each attachment screw, FIRST turn 1/2 turn COUNTER-CLOCKWISE to release the dog-ear mounting tab from its storage location.

Then tighten the mounting tabs by turning the screw CLOCKWISE until tight onto the top of the ceiling surface. Adjust the torque to meet the characteristics of the ceiling material DO NOT For use in thick ceilings – By default, dogear tab is in the middle of the travel and for most ceiling depths it can be used as it is. For thick ceilings where the tabs need to be at their highest position, turn all the screws COUNTER-CLOCKWISE till the hard stop (while making sure the tab is not held in the middle), before inserting the speaker through the ceiling cutout.

Control 442C/T 2 dog-ears
Control 445C/T, Control 447C/TControl 447LP, Control 447HC,Control 440CS/T	4 dog-ears

When removing the speaker, rotate all the dogear screws in a COUNTER-CLOCKWISE direction until each screw stops. Once all the screws have reached a hard stop the dogears will be folded, and the speaker can be removed from the ceiling.

Make sure to support the speaker when loosening the dogear screws to prevent speaker from falling.

Step 9 – Connect a Secondary Support Line to SEISMIC

TAB – A tab is provided on the side of each speaker for connection to an independent secondary support point. Some construction codes require using this secondary support point, which requires connecting a support line to a separate secure support point on the building structure. Consult construction codes in your region.

IMPORTANT:

Control Contractor ceiling speakers can generate substantial vibration. A secondary support cable to the seismic tab should be used as a secondary support point in case the ceiling tile or support structure breaks.

Step 10 – Adjust Tap Selector – The tap selector switch is located on the front baffle. Adjust the tap setting before placing the grille and before applying signal to the speaker. In some installations it is advisable to leave the grilles OFF to allow final adjustment of the taps for the system.

"NC" = No Connection. (Do not use this setting with a 100V distributed system)

Figure 26: Tap Selector (Control 447C/T shown)

Step 11 – Insert the safety Tether fastening plug and Attach the Grille – The grille comes with a safety tether tied to it. Insert the fastening plug at the open end of the tether (which comes pre-attached to the grille) into the included socket on the baffle. Make sure the plug is inserted completely in the socket and does protrude out blocking the grille from attaching properly.

Figure 27: Ensure the plug is inserted fully

Then position the grill in front of the speaker, taking care not to run the tether cable directly in front of one of the drivers (or else it could buzz with vibration). Make sure the grille is held securely magnetically in place such that it will not loosen or fall due to vibration.

Figure 28: Connection Pins on various models

To wire Control 400 Premium Coverage Series loudspeakers simply connect the positive wire to the “+” pin and connect the negative wire to the “-” pin. The “IN” pins are in connected to the “LOOP THRU” pins (+ and - respectively) inside the loudspeaker. The “Loop Thru” pins allow a parallel connection to an additional loudspeaker.

To select the operating mode or desired transformer tap of the loudspeaker, simply rotate the tap selector switch located on the front of the baffle to the desired setting.

Note: Both 70V/(100V) connections and low impedance connections are made via the same input pins. When using the transformer tap selections, be sure that the power amplifier is set on 70V/(100V) mode and the leads feeding the system are connected to 70V/(100V) outputs on the amplifier.

Hookup Schemes for Subsequent Speakers

Using Loop-Through Terminals -- By connecting the wire pair of a subsequent speakers to the "Loop Thru" on the Control 400 Premium Coverage Series Loudspeakers all subsequent speakers will be disconnected when this speaker's connector is disconnected during troubleshooting. This can be useful to isolate problems to a section of the distributed line while leaving the wires attached to the connector.

Hookup Schemes for Subwoofer-Satellite Systems Using Control 440CS/T and Control 442C/T

The Control 440CS/T subwoofer features a built-in crossover network designed for use with the Control 442C/T Ultra-Compact Satellite loudspeakers. Two or four Control 442C/T satellite loudspeakers can be used with the Control 440CS/T to create an extremely natural sounding and powerful subwoofer-satellite system that is perfect for applications requiring wide bandwidth and superior sonic performance with minimal visual impact. Using four Control 442C/T satellite loudspeakers with a Control 440CS/T will offer approximately twice the area coverage of a system using only two Control 442C/T satellite loudspeakers.

The Control 440CS/T and Control 442C/T Sub-Sat system can be driven either via a 70V/(100V) distributed line or in low impedance direct mode. The Control 442C/T speakers need to be set for low Impedance (16Ω) operation using the tap selector and connected to satellite output connectors located on the Control 440CS/T. With the Transformer Tap/Bypass switch set to the bypass/8Ω low impedance mode, the Control 440CS/T subwoofer itself presents an 8Ω load on your amplifier, and a two-satellite system also creates an 8Ω load on your amplifier, whereas a four- satellite system creates a 4Ω load.

Choose whichever of the following hookup patterns best accommodates your installation. All satellite speakers must terminate at the Control 440CS/T subwoofer.

Connecting the Control 442C/T Satellite to the Control 440CS/T Subwoofer.

Satellite Home Run to Subwoofer -- There are four satellite output connectors on the Control 440CS/T. If using only two Control 442C/T satellites, connect each loudspeaker to a single output connector as shown in the diagram below; one Control 42C in "Sat 1" and the second Control 42C to "Sat 2" ONLY. "Sat 3" and "Sat 4" connectors should not be used.

Use only either two or four satellite loudspeakers as described in the recommended configurations. Do not use one or three satellite speakers, or it could result in uneven sound levels and / or damage to your sound system.

Note: Apart from Satellite-Subwoofer application, Control 442C/T can also be used independently in either low-impedance (16Ω) or in a 70V or 100V distributed speaker line setting.

7. PAINTING THE GRILLE

For Premium Coverage Series models, the grille's white finish complements most decor and does not need further finishing. Where the interior design requires it, these grilles are easy to paint. The grille covers the entire speaker, so it can be painted prior to speaker installation.

IMPORTANT:

DO NOT paint the baffle of the speaker. Having paint between the magnet and the grille would diminish the ability of the magnets to hold the grille.

For best results, it is recommended to use the following procedure:

• Gently remove the grille backing material from the back of the grille without tearing it. Set it aside for re-application after painting. Either mask or remove the grille logo (for reapply after painting). Do NOT remove the edge trim.
• Clean the grille and edge trim with a light solvent such as mineral spirits by rubbing the item with a lightly dampened cloth. Do not, however, use abrasives such as sandpaper or steel wool (which can remove the grille's rust resistant plating). Do not use gasoline, kerosene, acetone, MEK, paint thinner, harsh detergents or other chemicals. Use of these cleaners may result in permanent damage to the grille assembly. Do not sand the grille.
• Spray one or more thin coats of paint. Be careful not to fill in the perforation holes (they are needed for the sound to go through – occluding them will harm the sound quality of the speaker).
• After the paint has thoroughly dried, reinstall the grille backing material to the back of the grille. If the grille backing has shrunk since removal, stretch it back to size to mask properly. If the grille backing has stretched since removal, trim to size.
• If the tackiness remaining on the back of the grille is not enough to securely hold the backing material in place (or if it got covered over by the paint), apply a very light coat of spray adhesive to the back of the grille.
• Lightly spray the adhesive to the BACK OF THE GRILLE rather than to the front of the backing material. If an adhesive says to spray both sides, use a different adhesive. Spraying adhesive on the front of the backing material can expose glue to the open air through the perforations, which can attract and hold dust from the air, impairing the clean look of the speaker.
• DO NOT place the front of grille on any surface where additional adhesive may have been sprayed. Doing so can deposit adhesive on the front of the grille surface, and similarly attract and hold dust and dirt.
• If the JBL logo was removed (rather than simply being masked), re-apply the JBL logo to the center of the grille. There is a shallow indent in the center of the grille to indicate where the logo goes.

Mask the Speaker If the Ceiling Gets Painted – The speaker itself should not be painted. The grille completely covers the speaker, and the speaker's front baffle is black to properly disappear visually behind the grille and grille backing material. If the ceiling gets painted after the speaker is in place, it's important to fully mask the speaker (including the edges of the baffle) prior to such painting so that no paint gets onto the drivers, or onto the baffle where any inconsistencies in color may be visible through the grille.

8. MAINTENANCE

No maintenance is required when installed in accordance with installation and wiring guidelines described in this manual.

9. REPLACEMENT PARTS

There are no user serviceable parts inside these speakers. Refer servicing to an authorized JBL Service Center. For the name of an authorized Service Center in your area, contact JBL Professional at the appropriate address from those listed on page 5.
